I don't if unix4j supports j2se 6, if supports you can assign the compile fit 
j2se 6.

Unix4j makes use of some java 7 features, for instance posix file flags in the 
ls command.

However, we have tried hard to make unix4j compile also with jdk6. Compilation 
however is not possible with target version 6, i.e. we cannot support both jre6 
and 7 with the same jar. See for instance here:

ty-with-jdk-6

Unfortunately there are some minor elements in our 0.3 code that are not 
compliant with jdk6. We have fixed those problems and 0.4 will be compatible 
with jdk6. You can download the sources (e.g. via git clone) and do a maven 
install:

git clone https://terzerm@code.google.com/p/unix4j/
cd unix4j
mvm clean install
